First Edition and Supplements
In 1957 German astronomer Wilhelm Gliese published his first star catalogue of nearly one thousand stars located within 20 parsecs (65 ly) of Earth, listing their known properties and ordered by right ascension. Items from the first catalogue were designated GL NNN and the stars were numbered from 1-915.
He published a significant update to his original catalogue as the Catalogue of Nearby Stars in 1969, extending the range out to 22 parsecs (72 ly). The update extended the list to 1,529 stars, and the stars were then designated Gl NNN.NA and numbered from 1.0 to 915.0. New stars not in the original Gliese catalogue were given fractional numbers to slot them 'between' existing Gliese stars to retain the existing right ascension order.
A supplement to the catalogue, published in 1970 by Richard van der Riet Woolley and associates, extended the range out to 25 parsecs (82 ly). This supplement added catalogue numbers in the range 9001–9850 using the now deprecated Wo prefix. Stars in this range now also use the GJ prefix.

Famous quotes containing the words edition and/or supplements:
“I knew a gentleman who was so good a manager of his time that he would not even lose that small portion of it which the calls of nature obliged him to pass in the necessary-house, but gradually went through all the Latin poets in those moments. He bought, for example, a common edition of Horace, of which he tore off gradually a couple of pages, read them first, and then sent them down as a sacrifice to Cloacina: this was so much time fairly gained.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“When science is learned in love, and its powers are wielded by love, they will appear the supplements and continuations of the material creation.”
—Ralph Waldo Emerson (1803–1882)
